Simultaneous Occurrence of a Midline Sublingual Dermoid Cyst with Respiratory Epithelium and Submental Dermoid Cyst in a Paediatric Patient: A Case Report and Review of Literature

Abstract

This report throws light on midline lesions of the oral cavity and hopes to add this rare case into the current differential diagnosis of the same.

Diagnosis, management, and follow-up of extensive dermoid cyst of the submental region

“…On the other hand, teratoid cysts, contain tissues derived from the three germ layers (endoderm, mesoderm, and ectoderm) 1 , 6. In general, these cysts have thin walls (2 to 6 mm thick) and often contain a yellowish oily material, representing keratin and sebaceous material 6 , 8. In our case, the histopathology was consistent with a DC.…”

“…The differential diagnosis of expansive sublingual lesions can be clinically challenging due to the clinical similarity with several lesions frequently observed in this region 7. The nonspecific clinical presentation and the rarity of DC make differential diagnosis wide and include infectious lesions of the salivary glands (sialadenitis), ranula, epidermoid cyst, lipoma, hemangiomas or lymphangiomas, sialoliths obstructing submandibular duct, branchial cleft cyst, and thyroglossal duct cyst 4 , 6 , 8. In our case, the differential diagnosis included conditions commonly observed in adults patients, and the hypotheses included plunging ranula, dermoid cyst, and epidermoid cyst.…”

“…The lining of the cyst is composed of orthokeratinized squamous epithelium with a prominent granular layer, and a cystic capsule composed of dense connective tissue. The lesion typically contains skin appendages, such as sebaceous glands, hair follicles and/or sweat glands 1 , 4 , 6 , 8 , 10. The presence of cutaneous adnexa is the main histological difference with epidermoid cysts.…”

Concurrent Pediatric Lingual and Submental Dermoid Cysts: Case Report and Literature Review

“…Although no standard treatment algorithm exists for treating lingual and floor-of-mouth dermoid cysts, surgical excision is the treatment of choice for these lesions. Most lingual and sublingual dermoid cysts can be removed with an intraoral approach, while submental dermoid cysts are best removed through an external approach [ 13 , 21 , 22 ]. In contrast to anterior lingual dermoid cysts amenable to a midline glossectomy approach, the relatively posterior position of our lingual dermoid cyst within the lingual septum made an inferior approach through the midline mylohyoid to access the lingual septum between the geniohyoid and genioglossus muscles the preferred approach.…”
